In the drawings, a preferred form of the invention is shown embodied in apparatus adapted to arrange green brick in superimposed rows upon trucks which are afterwards In the illustrated embgdiinent of the invention the various moving parts of the apparatus are preferably mounted upon a frame which, as shown, may comprise a plurality of vertical members 40 tied to each other by transverse members 41 and longitudinal4 members 42l (see Fig. 1). Extending forwardly from the members 40 are horizontally disposed members 44 which have their forward ,ends `supported by vertical members 45. It will be noted that the frame is so constructed that trucks 48 may be abvanced therethrough, -the trucks being advanced between the vertical members 45 and between the vertical members 40. As shown, the trucks 48 are preferably provided with front and rear axles 50 and 51, respectively, which journal. wheels 54`are arranged to travel upon tracks 55 (see Fig. 2).

Any suitable means may be provided for driving the improved apparatus. Thus, a pulley 56 is shown which may be connected by a belt, or'the equivalent, to a counter-shaft or the like. The pulley 56 is fixed -to one end of a shaft 57 which is rotatably journaled inv a bracket 58 mounted upon one of the transverse members 41 (see Figs. 2 and 9).` Sel cured to the other end of the shaft 57 is a pinion 59 which meshes with a gear 60 rotatably journaled upon a shaft 61 which is, in turn, rotatably journaled in the bracket 58. The gear is provided with a hub- 62 upon which a ratchet 63 is mounted, the ratchet 63 being rigidly secured to the gear 60 by bolts 64 which also secure a bevel gear 65 to the gear 60. Meshing with the bevel gear 65 is a bevel gear 66 fixed to a shaft 67 which is rotatably ]o,urnaled in the bracket 58 and in bearing blocks 68 mounted upon brackets 69 carried by the members 44 (see Fig. 5) and mounted upon the shaft 67 and constrained to rotate therewith is a pulley 70, which is aligned with a pulley 71 mounted upon a shaft 72 disposed on the other side'of the machine, the shaft 72 being rotatably journaled in brackets 73 carried by the members 44. Trained'over the pulleys 70 and 71 .is a belt 75 formed of any suitable material.

Referring now to Fig. 9, a disc 77 keyed to the shaft 61 carries a pawl 78 which is pivoted to the disc by a pin 79, the construction being such that the pawl 78 may engage the teeth of the ratchet 63. The pawl 78 is provided with an extension 80 engageable by a movable core 81 forming part of a solenoid 82 mounted upon the bracket 58 (see Fig. 11) When the extension 80 is engaged by the core 81 the pawl is held disengaged from the teeth of the ratchet 63, but, as hereinafter set forth in detail, the solenoid 82 may be energized to retractv the core 81 whereupon the pawl 78 will engage the teeth of the ratchet 63 so that the shaft 61 will be constrained to rotate with the gear60.

Keyed to the shaft 61 is a sprocket'85 which meshes witha sprocket chain 86 arranged to mesh with a sprocket 87 keyed to a shaft 88, the shaft 88 being journaled in bearing blocks 89 carried by the vertical members 40 (see Fig. 3). Fixed to the shaft 88 is another sprocket 91 which meshes with a sprocket chain 92 arranged to mesh with a sprocket 93 fixed to a shaft 94. Referring to Fig. 4, it will be noted that one leg of the sprocket chain 92 is trained over an idler 95. The shaft 94 is j ournaled in the frame and is provided with a bevel gear 97 which meshes with a bevel gear 98 mounted upon a vertically disposed shaft 99 also rotatably journaled in the frame (see Figs. 30 and 31). Keyed to the shaft99 are cams 100 land 101 which cooperate with anti-friction rollers 103 and 104, respectively, to oscillate a bracket member 106 pivoted upon a pin 107 mounted in the frame, the rollers 103 and 104 being carried by the bracket member. Secured to the bracket member 106 is a bracket member 108 to which one end of a link 109 is pivoted by a pin 110. The other end of the link 109 is pivotally connected to one end of a bar 112 slidably journaled in the members 44 and the other end of the bar 112 is provided with a lug 114. Itis readily understood that rotation of the shaft 99 causes oscillation of the bracket member 106 and it, in turn, reciprocates the bar 112, the bar 112 being connected to the bracket member by the link 109 and the member 108. The purpose of this construction will presently appear.

Beferringnow to Fig. 3, a pinion 115 fixed on the shaft 88 meshes with a gear 117 secured to a shaft 118 which is journaled in the frame, the shaft, 118 having sprockets 120 fixed thereon meshing with sprocket cha-ins 121 which also mesh with sprockets 123 fixed to a shaft 124 rotatably journaled in the frame. Each of the sprocket chains 121 has a plurality of attachments 125 pivoted thereto, pins 126 being provided for this purpose in brackets 127 plvotally mounted upon elongated intles 129 formin parts of the chain (see igs. 17, 18 and 19 Each attachment 125 terminates in a pair of spaced lugs 131 adapted to carry pallets or plates 133 upon which
